What do you want to know about a company to work there?

I run a jobs list for 166 startups in New York City that delivers weekly job openings across all the startups (including YC funded ones). I have this gut feeling that the traditional job posting / job description is out dated and doesn't provide enough information. We have thought of things like a video tour of the office, linkedin profiles of employees etc. If you were going to recreate the job ad / or the job page for the 21st century what would you really want to know about the company and the job to get interested?
